GDBus : Migrating to GDBUS and understanding the GVariants and GTypes

Question

GVariant is opaque data structure used in the GDBUS bindings for libDBus.

Its been mentioned that GVariant is a floating reference count system. What actually does a floating reference mean in this respect? Also, it is mentioned that the GVariant on calling g_variant_ref_sink() convert the floating reference into full reference.

May anyone explain what does this mean?

Actually i am not clear what is floating reference count. Can you explain me the same. — Gaurav, Mar 15 '13 at 11:47

The GObject documentation on floating references explains the concept. GVariant can't depend on GObject (it would be a circular dependency since gobject depends on glib and GVariant is part of glib), so it's not the same implementation, but it is the same concept.
